Clear SDA field

Perhaps this is an issue that has long been discussed somewhere. I have searched for it but still could not find the solution anywhere. In our environment, we send a container of SDA objects to UCR from HealthConnect. To populate the container we do a SQL query on a source system and then populate the appropriate SDA objects. Sometimes it happens that I want to do an update of a field and I want to empty the corresponding SDA field. In other words, send an empty string. The Alert.toTime field of the object in question is filled with the date '2022-11-29Z13:00:00'.

Hi All,

Hopefully someone can help me with this case. I need to encrypt a text(querystring) with an AES265 encryption. An other vendor is decrypting this information. I have a working class in C#. I've tried to build the same in Objectscript for the encrypt part but there's a missing link somewhere. What's the difference between the C# and Objectscript implementation?

Objectscript code (until now):

Is there a way to add specific table permissions to a security role programmatically? I'm working on scripting some of the initial setup work when we sell certain add-ons to our software, and I see how I can assign resources to a role and give it a description, but I don't see how I tell it that this role gives the user, for example, SELECT privileges only on the invoices table, or SELECT, INSERT, UPDATE, and DELETE.

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

When using VS Code for Objectscript, is there a way to directly open % classes, like %Library.String, without needing to search for a property of that type and right clicking->"Go to Definition"?

I know it is possible to use "system=1" in the workspace uri definition to see all the % classes, but that tends to clog up the left side viewer with many extra directories. There is also the option in the settings to selectively hide some by defining files.exclude, but it seems fairly complicated to set up a filter for exactly the relevant directories.

Hi folks!

How can I refer to a classmethod of the same class while coding another classmethod with Embedded python?

I know that I can call it with iris.cls(classname).MethodName(), but it's more cumbersome even comparing with ObjectScript, where I can call ..MethodName().

Compare ObjectScript:

do ..SetupGame()

and the same call in EmbeddedPython:

    iris.cls('eshvarov.sample.SeaBattle.GamePython').SetupGame()

Thoughts?

Let's consider these two ways of passing an obj to a function:

//var is a structured obj
(1) do ..methodX(var)
(2) do ..methodX(.var)

In c++ if we pass an obj by reference like in (2) we save a lot in computation because we are not copying the whole object, and when the object is modified within the function it is modified also for everyone.

In this case does (2) achieve any better performance than (1)? Is passing with the "." save any computation? the object is copied anyway?

Is there a simple way of passing obj to a function?

I have created a class file that I want to execute daily to gather Metrics (Message Header, Space Available, etc..) and write the data into a Cache table. Now that I have written the class I want to add it to the Task Scheduler within Ensemble to run every morning. How do I go about getting the class file created as a Task within the Task Scheduler? The Documentation isn't as clear cut for creating custom tasks as one would expect.

Hello,

I need to run some clean up routine in the background so loss of my terminal session won't stop the process.

I found the JOB command in the documentation.
JOB | ObjectScript Reference | InterSystems IRIS Data Platform 2022.1

When I try it, it doesn't seem to be doing much. I also expected this to become visible in the Background Tasks but that doesn't happen either.

Probably I am missing something.
